-feed of the chlorine under pressure can be read-.1

ily and easily regulated to vary. the strength of such chlorinev or other gases utilized for bleaching, sterilization or other purposes, the device being of novel construction-` A further object of the invention is the provision of a device of this character, which is simple in its construction, thoroughly reliable and effective in operation, compact, manually controlled, and inexpensive to manufacture and install.

With these and other objects in view, the invention consists in the features of construction, combination and arrangement-of parts as will be hereinafter more fully described, illustrated in the accompanying drawing, which discloses the preferred embodiment of the invention and pointed out in the claims hereunto appended.

In the accompanying drawing:

Figure l is an elevation partly in section of the device constructed in accordance with the invention.

Figure 2 is an enlarged fragmentary top plan view showing the indicator for regulating the feed of chlorine or other gases.

Figure 3 is a sectional view on the line 3-3 oi Figure 2 looking in the direction of the arrows.

Similar reference characters indicate corresponding parts throughout the several views in the drawing. y l

Referring to the drawing in detail, A"deslgnates generally a case which is provided with a door, a portion thereof being shown at B having a transparent panel C. Adapted to be disposed within and depending a distance in said case A is a substantially U- haped glass tube 5\for the This tube 5 at one -ofits vertical legs is joined with I a valve casing 1 for a hand operable valve (not shown) the stem 8 'of which is fitted with a hand wheel 9 while the other leg is joined by a coupling hose I with a T unionII connected to the provi- Serial No. 145,891

and between a flow reducer I2 and a discharge hose I3, respectively.

the form of an o rice a four-way union I4 the branch yI6 casing 1. The branch with a pressure gauge has communication `with ing 20 which is also in This flow reducer I2 is inand has connection with the branch I thereof,

having connection with the valve I1 has communication I8 while the branch I9 a gas control valve cascommunication through a tube 2| with a chlorine or other gas pressure tank A22 equipped with valve 23 as'is usual, the gas valve mechanism within the casing The casing is forme 2l) being hereinafter described.

d interiorly thereof with a partition 24 provided with a needle valve openlng needle valve l21. with an internally 25 and a valve seat 26, respectively, for a This needle valve 21 is fitted threaded socketed cap 28 adjustably threaded at 29 with the casing 20 so that by the turning of toward and away the cap the valve 21 will move from the opening 25 and when engaged therein-will become seated at 26 in said casing. In this manner the chlorine or other gas flow from the tank 22 will be regulated for admission to the tube I3 device. J

Fitted by clips circular dial 3| .which in the working of the su with the easing zo is a naif projects laterally to one side following ahorizontal plane with respect to said casing 20 and this dial is provided with indicia presenting independent scales or calibrations 32 and 33, respectively,

as well as temperature indications 34 of high and low degree, the low temperature indication being associated4 with the scale 32 while hpose presently described'.

the high temperature indication is in association with the scale 33 for a pura hand operated cut-off Fitted for rotary adjustment upon the cap 29 through engagement of a clamp terminal pointer about the same is a 35 36 for correct setting thereof and accurate cooperation of the same of the device. When closed, the pointer 36 zero mark of the scale with the scales 32 and 33, respectively, inthe use the needle valve 21 is should coincide Iwith the 33 and in this manner indicating the fact that the said valve is in closed position. The clamp 35 includes a releasing screw 31 permitting the pointer when the occasion requires reading of the pointer with the scales 3 The cap l 36 to be adjusted forv accuracy lin the dial through coaction of said 2 and 33 on the dial.

28 and the valve 21 carried thereby have in association therewith a hand crank orl handle 38 for manual turning of .said cap and valve in regulating the feed of gas from the or cock 'I is opened.y

tank 22 through the tube 5 on the opening of the valve in the casing 'I or directly through the tube I3.

In the use ofthe chlorinator, either during high or low temperatures, it is required that the valve 21 be adjusted. When the temperature is low the said valve 21 must be opened more than it need be opened when the temperatures are higher to effect the same pressure reading on the pressure gauge I8 and thus to have the .pointer 36 indication consistent', it is required that a reading of the scale 32 present onthe dial 3| be had when colder temperatures prevail while a reading of the scale 33 in cooperation with the pointer 36 is had when higher temperatures prevail and thus accuracy in the adjustment of the valve 21 can be assured accordingly thereto.

In the operation of the device the gas from the tank 22 in the feed thereof to the tube I3 can be had by setting the valve 2'I and on opening the valve within the casing I the ow of gas will by-pass the reducer I2 through the tube 5 containing water or solution 6 and such gas passes through the water o'r solution 6 in the tube 5 mixing-.with the latter and finally passing into the tube I3 and discharged therefrom for application. The pressure gaug-e I8 and the pointer 36 cooperating with the scales 32 and 33 on the dial 3| give the pounds pressure of the gas being dis.- charged through tube I3 from the tank 22, the pressure gauge I8 being a check on the pointer 36 in cooperation with the scales 32 and 33 in the Working of the device.

The pressure gauge I8 is indicative of the gas pressure in tube S'while the pointer 36 coacting with the scales 32- and 33 indicates pressure at the reducer I2. can be obtained commercially from many chemical plants as will be understood. As has been stated, the tank is provided with the cut-off valve 23 for controlling the discharge of the gas therein and saidxtank, as is customary, is placed on the weighing scales 39.

As soon as the gas valve 21 isz op'en, the water level in the U pipe 5 will move when the valve As the gas goes through the U tube 5,- the liquid in the U tube will move to a vertical position von the right leg where the gas will passthe liquid in the said tube and then the liquid will drop back to the origina-l position and the liquid will pulsate back and forth as long as there is gas going through the said tube 5 and the valve or cock I is open. This U tube 5 is used only for setting the pointer`36 on zero and for by-passing the gas through the said tube 5 so that the water level will show n0 denite Water pressure. i' Y e What is claimed is:
